SHOE-PEGGING MACHINE.

srscrmcarroiv forming part of Letters Patent No. 735,499, dated August 4, 1903.

Applicationfiled December 13, 1902. Serial No. 135,046. (No model.)

To all whom) it may concern:

Be it known that I, EUGENE HAMEL, a citizen of the United States, residing at Lynn, county of Essex, State of Massachusetts, have invented certain new and useful Improve; ments in Shoe-Pegging Machines; and I do hereby declare that the followingis a full, clear, and exact description of the-invention, such as will enable others skilled in the art to IO which it appertains to make and use the same. This invention relatesto machines for pega ging boots and shoes or other materials to secure the soles to the uppers thereof, audit is of that class of pegging-machines which automatically severs the pegs from a strip or ribbon of peg-woodthe width" of which'is equal.

to the length of the pegs.

The main object of my present machine is to so simplify the construction of the ma- 2o chine as to enable it to perform all the work performed by former machines of this class with greatly-simplified construction and a fewer number of parts, thus enabling the parts to be more strongly built and rendering the machine less liable to repair as well as more accurate in its movements.

A special object that Ihave in view is to improve the peg-cutting mechanism in such manner thatit will be no longer necessary to set the machine by means of clamp-screws, dials, and other apparatus for each thickness of leather or other material and each individual shoe or set of shoes that are pegged in the machine; but,.on the contrary, the ma chine is always ready for use in any thickness of leather and will cut the pegs to the proper lengths at every point of the operation.

To these and other ends my invention consists, primarily, in .reversingthe process heretofore in use of cutting pegs of the proper length from the peg strip or ribbon, which former process consisted in first cutting the ribbon lengthwise to form a peg of the proper length, and, second, in splitting or slicing off 5 a peg from the ribbon thus out, which peg Was pushed by proper mechanism into the plungerthroat and thence driven by the driving plunger or driver into the hole punched for it by the aw]. on the contrary, the pegis first sliced or split from the ribbon by the transverse knife, and

In my machine, I

thereafter such peg is cut to the proper length, and to this end it is caused to be pushed down in a guideway a certain distance, determined automatically by the thickness of the stock being operated upon, and then cut across by a V-shaped trimming-knife' operated at the proper time, so that the end of the peg out off falls away and the peg now trimmed to the proper length is pushed into the plungerthroat, as before. It will be observed in' the sequel that this mode of operation has great advantages over the other, primarily in enabling any width of ribbon to be'used and in enabling the peg to be pointed at the same 6 time that it is cut by the V-shaped form of the knife.

My invention further consists in replacing the complicated mechanism which was heretofore employed to regulate and'set the trim- 7o mingknife automatically by the "vertical movements of the born or other work-support caused by varying thicknesses of stock by'a simplified mechanism consisting of a horizontal reciprocating cam which limits the downward movement of the reciprocating bar, to

which is attached the pusher which pushes down the cut pegs successively to the proper distance to be acted on by the trimmingknife.

My invention further consists in the peculiar constructions and combinations Which will be hereinaftermore fully described and claimed.

I have illustrated my improvements in the accompanying drawings, wherein- Figure 1 is a side elevation of a complete machine embodying my improvements. Fig.

Fig. 16 is a detail view of the parts carrying the peg-strip, showing the mode of trimming the pegs.

The same numerals of reference denote like parts in all the figures of the drawings.

As will be observed from the following specification and claims,the parts embodying my improvements lie exclusively in the upper part of the machine and relate to the workhead, which is designated by the numeral 16, the lower portions of the machine comprising a pedestal or standard 17 and a base-piece 18, to which it is secured and on which it rests and which are of the same form as in common use on this type of machine. At the upper end of the work-head 16 is journaled the usual horizontal front to rear main shaft 19in journal-boxes 20 and having fast and loose pulleys 21 thereon, which operate the various working parts when the machine is in motion. About half-waydown the standard 17 is journaled in a long bearing-box 22 the rock-shaft 23, carrying on its forward end a cylindrical vertical head 24, in whichis reciprocably mounted the shank 25 of the'horn 26, while the other end of the shaft 23 has fixed thereto by means of'an adjustable segment 27 a rock-arm 28, which is caused to oscillate backward and forward at each complete rotation of the shaft 19 by-means of the cam-roller 29, which is operated by a camwheel 30. The upper end of the horn 26 carries, as usual, an anvil 31, on which the shoe rests while being pegged and which supports the latter against the blows of the awl and pegdriver, while the lower end of the shank 25 of the horn is connected by a ball-joint 32 with a link 33, pivoted by a double or universal joint piece 34 to the treadle-lever 35, which is pivoted at 36 to the frame at the lower end of the standard 17. The treadlelever has at its front end a foot-plate 37 and at its rear end is overbalanced by a counterweight 38, being partially supported, as

movement of an amplitude equal to the distance between the successive pegs of the shoe.

On the front of the work-head 16 is mounted, as heretofore, a rocking head or block 42, which is mounted to oscillate on a pin 43, secured in the head 16 by means of a nut 44. This rocking head is given a very slight oscillatory movement, such that its lower end has an amplitude of movement equal to that of the anvil 31, so as to coact with it in feeding forward the shoe during the pegging-operation, and this motion is given to the rocking head 42 by means of a small eccentric camblock 43, operating between the two rollers 44*, on opposite sides thereof, carried by the two upstanding limbs 45, formed on the upper end of the rocking head 42, which is thus bifurcated, so as to receive the cam-block 43 between the two limbs.

The rocking head 42 carries a vertically-reciprocating plunger-bar46,which slides upand down in a suitable recess formed for it in the rocking head and whose front side is covered by a plate 47. The upper end of the plungerbar 46 has an enlarged head 48, which carries a trundle-roll 49, mounted thereon and operating in a groove 50, formed in the face of the cylindrical cam-block 51, secured on the shaft 19, as shown, so that at the same time that the head 42 is being oscillated or otherwise moved from side to side the plunger-bar 46 is raised and lowered. At its lower end the plunger-bar 46 has formed therein a semicylindrical groove 52 for the awl 53, which is secured on the plunger bar by a grooved clamping-block 54 and a screw 55. Side by side with the awl is mounted also the pegdriver 56, which is likewise secured to the plunger-bar 46 by a clamping-block 57 and screw 58, the driver 56 being held in parallel relation to the awl and its lower end being arranged to reciprocate in the tubular throat or guide 59, which is formed as a lug on the side of the guide-plate 60. (Shown in Figs. 10 and 11.) The guide-plate 60 is secured to the lower end of the rocking head 42 and oscillates with it and has, as shown, a turnedup flange 61 on its lower side, in which the peg-strip 62 runs. Any suitable mechanism may be employed for feeding forward the peg-strip, such as the usual pawl-and-ratchetoperated pair of gripping-wheels 62; but this forms no essential part of my present invention, and any of the well-known forms of feeding mechanism may be used therein. The flange 61 on the guide-plate 6O terminates ab- ICO ruptly short of the plunger-throat 59, leaving end of the peg-strip; but the left-hand side,

of this extension, as shown in Fig. 10, also terminates short of the right-hand end of the flange 61, so as to leave room for the passage of the detachingknife 65 between them. When, therefore, the detaching-knife is operated to sever a peg 66 from the strip of material being fed along the guide-plate 60, it passes between the flange '61 and the extension 64, and the end of the strip is carried under the latter, so that the detached peg is retained thereby. As, however, the lower end of this extension is open, it is necessary to provide means for supporting the detached pegs, which are normally two or three in number, (indicated at 66, 67, and 68,) and to this end I provide a spring-plate 69, having a hole 70 at its upper end through which passes a screw 71, securing it to the upper end of the extension 64, and the lower end of the springplate 69 carries a small friction-block 72, which extends within a recess 73, formed in the lower end of the extension 64, and presses upon the several detached pegs 66, 67, and 68, thus preventing them from falling, while at the same time permitting them to be readily pushed either sidewise or in a vertical direction. The feeding mechanism will cause the strip 62 to be pushed along'step by step and at each motion will push the foremost peg 68 into the throat 59 and directly under the driving-plunger'56, by which it is immediately driven down and set in the stock; but

before this takes place the peg is trimmed, if required, to the proper length in the following manner: The extension 64 has a longitudinal slot 74 therein, in which reciprocates the bent finger 75, formed on the lower end of a pusher 76, which is clamped to a vertically-reciprocating pusher-bar 77, the mounting and operation of which will be described hereinafter. The vertical reciprocation of the finger 75 is such as at each revolution of the shaft 19 to push down, if rea sharp point, as indicated in Fig. 16, and

quired, the detached peg 67 the requisite amount, so that it will be cut ed to the proper length by the trimming-knife 78, which is rigidly mounted, with the detaching-knife 65, in the manner which will be presently described. This trimming-knife has a channeled or V-shaped edge, asindicated in Figs. 13 and 14, so as to cut the peg crosswise to the trimmed-ofE-remnant 79 will drop on the floor or into any suitable waste-receptacle provided for it. The peg is thus not only trimmed to theproper length, but also pointed by a V-shaped cut at right angles to the V- shaped edge of the peg-strip 62, which is already formed thereon, as usual, for use in the machine, as indicated by the section in Fig. 9. t j

Thetwo knives and 78, which respectively detach the peg and trim it to the proper length, are both mounted rigidly on the lower end of a knife-holder 80, which is generally of plate form and is pivotally connected at its upper end by means of a pin 81 to a lug 82, formed on the rocking head 42, while at an intermediate point of its length it is connected by a pin 83 with the lug 84, secured to the stationary head 16, this connection being such as to enable the free vertical movement of thp knife-holder relative thereto by means of a rectangular block 85, sliding in-a guide-slot 86, formed in the knife-holder, and the latter is further guided in its movement against wabbling by a projecting lug 87, which is recurved, so as to support both sides of the knife-holder. On its lower end the knifeholder has an aperture 88, through which passes the clamping-screw 89, which secures the two knives to the knife-holder; but any other means may be employed for this purpose. The trimming knife 78 is formed as a projecting lug at the lower side of a block 90, which has a horizontal fin 91 formed on its inner side andfitting into a corresponding groove 92 in the lower end of the knife holder, and the block is further provided with an elongated horizontal slot 93, through which the screw 89 passes. On its opposite side the block "90 has formed therein between the face of the block andthelug 78a horizontally-extending groove 94, on which rests the lower edge of the knife will thus be seen that the two knives may each beadjusted laterally independently of each 01 her and the knife-holder and clamped in the desired position, thus allowing for wear, while at the same time the fin 91 and the groove 94 prevent any possible twisting ordisplacement of the knives. The oscillating movement given to the rocking head 42 by the mechanism hereinbefore described is such as to cause the knife-holder 80 to have likewise a slight horizontal oscillating movement, so thatwhen the lower end of the rocking head moves to the right as seen from the front, Fig. 3, the knives will be withdrawn from the peg-strip and the latter maybe fed forward ready for driving another peg, and when the lower end of the head 42 is moved toward the left the knife-holder 80 will be caused to oscillate about the pin' 83 as an axis and both knives will be caused to cut the pegstrip, as before related, the detaching-knife 65 cutting oif a peg and the trimming-knife 78 trimming a preceding peg to the proper length, and at the same operation the plunger 56 is thrust downwardly to drive the peg directly beneath it into the work. i

I will now describe the operation of the pusher 76, which is automatically operated to cause the peg to be cut toits proper length and which forms one of the most important and valuable features of my present invention. This pusher, as before described, is secured to the lower end of the pusher-bar 77 by means of .a clamping-block 96 and a screw 97, and the pusher-bar is secured by guidestraps 98 and 99 toreciprocate vertically on the cover-plate 47 of the rocking head. Near its upper end is attached, by means of a pin 100, one end of a coiled spring 101, whose other end is secured to a pin 102 on the lower guide-strip 99, the action of the spring 101 thus being to draw the pusher-bar downwardly to the lower limit of its "movement. On the right-hand side of the pusher-bar is formed a projecting trip-lug 103, which projects over a vertical slot 104, formed in the plate 47 and through which projects a pin 105, secured to the driving-bar 46 and reciprocating therewith. The action of the pin 105 striking on the lug 103 is therefore such as to raise the pusher-bar and pusher 76 at each rising movement of the plungerbar 46. The lower limit of movement of the pusher-bar 77 is formed by a projecting lug 106 on the opposite side of the pusher-.

barfrom the lug 103, on the end of which lug 106 is mounted a small roller 107, which rolls along the cam edge 108, formed on the horizontally-reciprocating cam-bar 109, whose forward end is guided by a strap 110, secured to the rocking head 42, and whose other end is formed cylindrical and passes through a guide-lug 111 at the rear side of the stationary head 16. Between these two points of support the cam-bar 109 has formed on its lower edge a series of rack-teeth 112,

which gear with a toothed segment 113,formed on theupper end of a bell-crank lever 1l4,pivoted on a pin 115, projecting from the side of the work-head. The other end of the bellcrank lever 114 extends rearwardly and is connected by a long connecting-rod 116 with the forward end of the treadle-lever 35, and at an intermediate point the rod 116 may be divided and have a turnbuckle 117 inserted therein for the purpose of adjusting its length and to properly regulate the position of the pusher with relation to the thickness of the stock, as will presently be described.

Itwill be observed that the cam edge 108 is formed of two horizontal portions 118 and 119, joined by an upwardly-sloping oblique portion 120, the purpose of this edge being to form, as above indicated, an adjustable lower limit for the movement of the pusher 76. It

will be seen that in the reciprocation of the pusher by the means hereinbefore described, consisting of the reciprocating pin 105 acting on the lug 103, the pusher will be caused to rise above the top of the series of pegs and peg-strip, at which position the peg-strip will be automatically fed forward and will feed one peg 67 directly under the pusher-finger 75. Thereupon the pusher descends, depressing the cut peg 67, and the farther down it dopresses it the shorter will the peg be cut by the operation of the trimming-knife 78, and therefore to cut the shortest possible pegs the extent, and the roller 107 must therefore rest on the lower horizontal portion 118 of the cam edge 108, so that in this case the cam-bar 109 must be in the position shown in Fig. 6. On the other hand, to cut the longest possible pegs the cam-bar must be drawn back until the lower limit of the pusher-bar will be in that position wherein the roller 107 rests on the upper horizontal portion 119 of the cam edge and the pusher-finger 75 will be depressed but very little and sometimes not at all. For intermediate lengths of peg the cambar must therefore be in intermediate positions, in which the lower limit of motion of the pusher will be regulated by the striking of the roller 107 on the oblique portion 120 of the cam edge 108. Now it will be observed that the connection between the anvil of the horn 26 or other work-support and the cambar 109 is such as to regulate the length of the peg out according to the thickness of the stock which is resting on the work-support or anvil 31 and held between it and the presser-foot 121, as shown at 122 in Fig. 4, for when the stock increases in thickness the horn 26 will necessarily be depressed, thus depressing the treadle-lever 35, causing the weight 38 to be raised and drawing down the connecting-rod 116, which latter through its connection with the lever 114 will cause the cam-bar 109 to be retracted, thus raising the lower limit of motion of the pusher-bar in the manner before described, and thus cutting oif longer pegs. On the other hand, in case the thickness of the stock should decrease the weight 38 will cause the horn 26, which presses on the lower side of the stock, to rise, and thus will push forward the cam bar 109, permitting the spring 101 to draw the pusher-bar farther down, and thus shortening the length of the pegs cut oif by the trimming-knife 78. If the turnbuckle 117 is properly set and the pusher 75 properly clamped to the pusherbar, so as to extend downwardly to the proper distance, the length of peg may be exactly regulated to the thickness of the stock, and this will be true for any stock whatever and at every point of the operation, and thus no preliminary setting of the machine for different thicknesses of leather is required after it has once been properly adjusted. The work is set in the machine in the usual manner by depressing the foot-plate 37.

The V-shaped trimming knife 78 is arranged to out against a triangular steel cutting-block 123, which is shown in reversed plan view in Fig. 8, and secured in position by the chamfered edge of a clamping-block 124, secured to the underside of the head 42 by a screw 125.

It will be seen that this improvement givesvery much greater simplicity of construction,

as well as efficiency in action over the old form, in that it avoids preliminary setting and substitutes simple and direct action with a minimum of operating parts. The pegs are not only enabled to be pointed instead of merely edged, as heretofore, by a four-sided l V-point, but, further, the width of ribbon or pegs used is immaterial and the operation of the machine independent of the character of the material pegged thereon.

While I have shown in the accompanying drawings the preferred form of my invention,it will be understood that I do not limit myself to the preciseform shown, for many of the details may be changed in form or position without affecting the operativeuess or right angles to the edge of the strip, means' utility of my invention, and I therefore reserve the right to make all such modifications as are included within the scope of the following claims or of mechanical equivalents to the structures set forth. It will also be obvious that my im pr'ovement is not restricted to the use of wooden pegs, as I also contemplate the use of pegs of leather and any other material which may be found suitable. I, however, wish to have it understood that although I have above described m y machine as employed for pegging boots, shoes,and leather generally the machine may be employed for any use whatever, and I do not wish. to restrict myself by the following claims to any particular use. i Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is
